摘要
目的研究分析肉桂的挥发性成分。方法采用水蒸气蒸馏法提取肉桂中的挥发性成分,用气相色谱-质谱(GC-MS)联用仪进行分析鉴定,并采用峰面积归一化法测定各成分的相对含量。结果共分离出36个化学成分,其中21个化学成分匹配度都在85%以上,占挥发油总量的80.67%。其中含量高于1%成分的有14个,以桂皮醛含量最高(41.86%),其次是棕榈酸(7.66%)、亚麻酸(7.65%)、甲氧基肉桂酸乙酯(5.36%)、d-杜松烯(2.82%)、亚油酸(2.22%)、香豆素(2.14%)、肉桂醛(1.92%)、丹皮酚(1.87%)、油酸(1.71%)、α-蒎烯(1.49%)、α-毕橙茄醇(1.48%)、去氢白菖烯(1.40%)和苯丙醛(1.09%)。结论肉桂挥发油中主要化学成分以芳香醛类、芳香酯类、脂肪酸类和萜类化合物为主,且多是15个碳以下的小分子化合物。
Objective To study and analyze volatile components of cinnamon.Methods Water vapor distillation was used to extract volatile components of cinnamon.Gas chromatography/mass spectrometry （GC-MS）apparatus was applied for analytic identification.Peak area normalization method was adopted to determine the relative content of each component.Results Thirty-six chemical components were separated.Of them,the matching degree of 21 chemical components was over 85％,accounting for 80.67％ of the total volatile oil.The content of 14 chemical components was over 1％,of those chemical components,the content of cinnamic aldehydre was the highest（41.86％）,followed by palmitic acid（7.66％）,linolenic acid （7.65 ％）,metoxy cinnamic acid ethyl ester （5.36 ％）,d-cadinene （2.82 ％）,linoleic acid （2.22 ％）,coumarin（2.14％）,cinnamyl aldehyde （1.92％）,phenol （1.87％）,oleic acid （1.71％）,alpha pinene （1.49％）,alpha-cadinol（1.48％）,calamenene （1.40％） and benzenepropanal （1.09％）.Conclusion The chemical components of cinnamon volatile oil are aromatic aldehydes,aromatic esters,fatty acids and terpenoid,which are the small molecule compounds with less than 15 carbons.
